I'm really sorry to hear about that happening. It is the first time I've ever heard of that happening. I really don't think it is the plugin that did it. I think it is just coincidence. It uses the same loading mechanism as Mach3. The signature is a CRC, and the bootloader is evidently corrupt. Can you run Mach3? I'll get this fixed for you. Please contact me at support@warp9td.com if the problem persists.
